. IMPROVEMENT IN HARVESTERS.

, Specification forming part of Letters Patent'No. 197,192, datedNovember 13, 1877; application filed April 25, 1877.

To all whom it may concern! Be it known that I, WILLIAM N. WHITELEY,

of the city of Springfield, county of Clarke, and- State of Ohio, haveinvented certain new and useful Improvements on Reapers and Mowers; andI do hereby declare that the" following is a full and correctdescription thereof, reference being had to the accompanying drawings,and to the letters and figures of reference thereon, wherein Figure 1 isa perspective view of my reaper. Fig. 2 is a plan of the same. Fig. 3 isa side elevation of the same. Fig. 4 is a detached plan of theoscillating gear. Fig. 5 is a horizontal section through themain-wheel-axis. Fig. 6 is a plan and elevation of the drivingpinionloose on the axle. Fig. 7 is a plan of clutch side of same. Fig. 8 is'aplan of main axle. Fig. 9 represents the chain-wheel clutch. Fig. 10shows the chain-wheel. Fig. 11 represents the chain guard and guide.Fig. 12 represents a bracket on the outer end of the main ax e.

The shaft is is stationary, and secured to the frame F by means of theboxes I and m. Between the boxes 1 and m, and rotating on shaft k, isfitted the master-wheel M. The outside of the hub of master-wheel isturned off at both ends, and on the outer end is fitted the outsidediiferential gear-wheel J. The wheel J revolves freely on the hub ofwheel M, and

is driven by means of a coupling-plate, I, and a pawl. The pawl can bedisengaged bymeans of handle a. ring Q by means of the pins T. On thegimbal-ring Q is secured the differential wheel B.

The four pins T form a universal joint, the

intersection of the cross-axis being common with the axis of the shaftk, which allows the internal differential gear R to roll on the wheel Jand give motion to the vibrating arm A, which is firmly secured to thewheel It.

The oscillating gear-wheel R is constructed with two lugs, l, projectingradially from its outer periphery, and an arm, m, extending in a lineparallel with its axis; and the vibrating frame A is constructed withfeet straddling over said wheel, so as to stand upon said lugs and besecured thereto by bolts, as shown. The frame A has also an arm orcross-bar, which seats upon the arm m, and is secured On box m issecured the gimbal I thereto bybolts, whereby these parts are firmlysecured together without shearing strains upon the holding-bolts.

In the outside end of the box m is fitted a small crank-shaft, 0, whichis connected to the arm A by means of its crank-pin. On crankshaft 0 isfitted a fly-wheel, n. The office of the crankshaft 0 and fly-wheel a isto control the motion of the wheel R and relieve the thrust of the knifeat the time of the stroke. In the end of the vibrating arm A a ball-pin,y, is attached, to constitute a joint for the pitman P, which isconnected to the knife-bar.

A chain-wheel, E, is fitted to the inner end of the master-wheel hub,and is driven by means of a coupling-plate, N, and pawl,. and isconnected by the chain c to the chain-wheel T, which is secured to therake-shaft.

The rakes guide-cam is mounted upon the arch V, which is firmly boltedto finger B and shoe 8.

A lever, 00, is bolted to the front end of the shoe 8, and by means ofsaid lever the cutterbar is tilted, and held in the required position bymeans of a spring-bolt fitting into notches on a rack-bar bolted to theframe F.

The cutter-bar B is attached to the frame by means of pins y and rollsupon them. On both sides of frame F arebolted tongue-trunnions 2, aroundwhich the tongue oscillates, and to which the tongue is connected by thehounds H.

On the front end of frame F the rack-stand q is bolted to carry a lever,r. The lever r is connected with the tongue by a link, and when operatedcauses the tongue to roll on the trunnions z, and so raise or lower thecut. On the inside of the master-wheel M, and fitted on shaft k, is apicker or ti ghtenin g-block, p, which serves to tighten the chain, whenslackened, by throwing the knife-guards downward, and also is useful infreeing the links from the chain.- wheel E. On the top of cam-shaft z arakehead, It, is secured, and carries four rakes, T. The rakes arearranged to rake the grain from the platform automatically once or twiceat each revolution of the master-wheel, as may be required; or, bytaking out a trip-pin, the driver may, at will, cause the rakes tosuspend their operation.

On the back of cutter-bar B is bolted platform P, which receives thegrain, and from which it is raked 011 into gavels, as may be deandplatform is carried by the grain-wheel W,

which can be raised or lowered to suit the height of the cut.

The differential gear-wheels J and R are partly covered and fullyprotected from the entrance of mud or dirt dropping from the edge of thewheel M by means of a shield-plate, S, which, for convenience ofattachment, is made in two parts, bolted to the edge of the wheel J, asshown.

I claim 1. The combination of a vibrating frame, F, having boxes I m tosupport a shaft, 7:, for the master-wheel, differential gear-wheels J B(one of which oscillates) upon the shaft outside of said main wheel,crank 0, outside of said frame, and a vibrating frame, A, whereby motionis transmitted to the cutters.

2. The shaft k, resting at one end in the box,

combined with the box m, to receive the other end of said shaft, saidbox m being provided with cross-bearings for the gimbals T T, and withan end socket to receive the crank-shaft o.

3. The diflerential wheels J B, one of which oscillates, combined withthe sectional shieldplate secured to the pawl-case, to prevent dirt,&o., from dropping oif the wheel into said gearing.

4. The oscillating gear R, provided with lugs l, radiating from thecenter, and projecting beyond the outer periphery of said wheel, and armm, parallel with the axis of said wheel, combined with the vibratingframe A, constructed with straddling feet adapted to stand upon saidlugs, and an arm or cross-bar adapted to seat upon the arm m, the wholeto be se cured there by bolts, as set forth.

WILLIAM N. WHITELEY.
